7 The object of any invention is'to" produce a mast hoist of cheap and light-construction and of rather'limited height capacity foruse in the elevation of building materials inthe' fabrication of comparatively low buildings.

The' accompa 11ying drawings illustrate my invention.

The "several sections are secured together,

as at X, in vertical alignment bychannels' 11 and 12 maybe secured iniplaice by i;

15 placed in the channels to bridge the'j'oint between two sections and securedby bolts 16. Detachably secured togthe top'of the top section of the masti's a pulley head comprising a pair of parallel anglembars 20, 21 and having depending gusset plates'22 to each ofwhich is secured an angle -23havingarms arrangedbparallel to the flanges ofthemast channels and spaced apart, in pairs, adis-- tance slightly greater than the depth of'said ceive bolts 24 byme'ans of which the structure may be removably secured position. J ournalled betweenthe cross bars 20,-21are Q 70 'cable27 may begpassed. :The 'uppe'r'fian'ges 1 of the cross angles 20, 21; are perforated to receive guy wire eyes 28 to two' pulleys 26, '26 over which a hoisting 29 may be secured.

The'outer ends of'channels 45 are connected to cross channel 54eby plates 50 hav-ing downturned ends 51' perforated to receive a shaft Secured to the angles"37"nea1"their lo'wcr V 52 upon which is pi'votally sup ported a tilting bucket 53 normally held by gravity, 1n load [supporting position against "a stop 58 of frame 35. Bucket 53 near its lip is provided with a roller 5 at each corner; 1 g

A ina'teritil-handling platform P comprises floor boards 56 secured to two angles 57 which may be arranged alongsidechannels L5 and bolted theretoand to brackets 59.

Theliead frame carries ahopper' to" which. [the first sectlon of a chute system. may beconnected and is of such form that the frame and the'duinping; bucket carried thereby 'may be carried upwardly therethrough in order to dump plastic material from the bucket into the'hop'per. V

y v This head frame comprises a pair of laterallyspaced angles 60, 60 of considerable vyei-tical extent connected top and bottom by cross bars 61 and carrying inwardly presented angles 62, 62 spaced from the cross bars v61 ,to form guide ways'63 for the reception of flanges 10 of channels 10. Securedto the up- "perendsof angles 60 are horizontal angles 70, 'ZO connected at their outer ends by. the cross z angle '71" and at thelr inner ends with the channel 5 72, the rectangular' frame thus 1 formed being braced by the gusset plates 73,

' Secured to the inner-faces'of each plate 80 are twoguides 84', 84 so formed, placed and 1 spaced that, asthe bucket nears-the upper end of its movement, therollers will: be soguidedas to cause the bucket' to. tilt and dump itscontents'into hopper 181' and then be free to be'mo vedfurther upwardly free from the *guidesand, upon the lowering ofthejfframe of a pair of longitudinal commercial channels 35 to actu pon said rollers to returnthe bucket to loadcarrying position.

i For the pnrpose of leading cable 27 to the hoist -drum I provide an angle section 90: adaptedto be detachablv secured to either one of the two lower cross channels 11 (which are preferably placed with their' flanges uppermost) and to this section 90 'Ipivotally'connect a pulley block-91 under the pulley of which the cable 27 may be led up. to the hoistingdrura' by 1 In c'ommercial'practice the'bucket is onlyof -2. A mast hoist correspondingly light and, therefore, cheap to manufacture and easy tohandle- It is prim'arily designed for use in connection with comparatiyely small ]ObS.' It will beunderstood, however; thatlv do iiotintcnd to unnecessarily limit my self to' an apparatus of any particular dimensions,f v Further bracing of the structure,'jother than the bracing from thetopframe, may be I found: to be desirable and for that purpose;

gay wires 95 may be attached to an arm 100, f

which-ma I cla1m y-be attached at any desiredheight.
